Perfect fit for my DIY amplifier

These knobs are exactly what I needed. The 6mm hole fits my potentiometers perfectly without any wobble. The aluminum feels premium and the finish matches my chassis nicely.

Sturdy and stylish

Great weight to them, not too light. They add a professional touch to my homemade volume control unit. Will buy again.

Excellent precision

Very precise boring makes installation a breeze. No need for extra adapters. Highly recommend for anyone building custom audio gear.

Good quality, slight color variation

Solid construction and easy to install. The silver is slightly brighter than in the photos, but it still looks great on my sound card project.

Best knobs for the price

I have tried many different knobs, and these offer the best balance of quality and cost. The grip texture is also very comfortable.

Works as described

No complaints here. They fit standard 6mm shafts well. Just make sure your shaft is clean before pressing them on.

5 FAQ

Q: What is the outer diameter of the knob?

A: The outer diameter is approximately 25mm, providing a comfortable grip for volume adjustment.

Q: Will this fit a 1/4 inch shaft?

A: No, the inner hole is precisely 6mm. A 1/4 inch shaft is approximately 6.35mm, so these will not fit without modification.

Q: Is the black version available?

A: Currently, we only stock the silver anodized version for this specific listing. Please check our store for other color options.

Q: Can I use these for rotary encoders?

A: Yes, as long as your rotary encoder has a 6mm shaft, these knobs are fully compatible.

Q: Do these knobs come with set screws?

A: No, these specific models are designed for a press-fit installation on 6mm shafts, but they can be secured with adhesive if needed.
